In order to monitor the transfer of systems and detect any issues with the process, a canned query has been provided, that can be monitored from within the destination server ePO - On-prem console. This canned query reports any systems that have failed the ePO - On-prem system transfer process, along with an initial root cause analysis of the failure.
It is recommended that this query be routinely checked during system transfers. A server task can be configured to automatically email the results of the query at regular intervals, if desired. For more information, please see the ePO - On-prem product documentation corresponding to your destination server version.
Note that the report uses the standard property collection mechanism of ePO - On-prem, and as such will require systems to perform an agent-server communication in order to obtain the most up-to-date properties. For this reason, it is common for reports to show inconsistent data due to an expected lag in property collection.
